Which eggs are old, and which ones are safe to use?

I confused last Sunday about eggs in the fridge since working long hours again and not good enough time to spend in the kitchen. They were out of the boxes and I had no idea which one is old, bought earlier, fresh enough for breakfast or not.
The best way is keeping them in their original box in the fridge then see the expire date..
Anyway,here is one easy way of aging eggs I want to share with you guys.

Fill up the glass with cold water and put eggs in it. As eggs age, they lose some of their moisture and  begin to float in water.


1- Really fresh egg  - Lies on the bottom the glass, flat.
2-At least one week- One end bobs up a bit, it is older, but still good. You might use them baking,   also ideal for hard boiling. Because fresh eggs are impossible to peel.
3-At least 3 weeks-  Top end touches to buttom first but won't sit on the bottom. It is getting old.       I personaly don't use floating eggs - No matter float low or high!
4-A floating egg is a bad egg. Don't use it!

Aria wanted an soft boiled egg instead scramled last Sunday and this knowladge from the site was so helpful! I used the older ones for a chocolate cake and decorated left over cookie crumbs:) 

I seperated  the eggs and had 2 eggs floating. I don't like wasting food though:(

 

Do you know any other way of aging eggs?

Spending time in the kitchen relaxes me..
